    water system parts

    1997 4788. What is the trade name of the parts used to construct the boats interior water system. I need some couplings replaced as they have cracked. These are plastic (poly propelene) compression fittings that couple the 1/2 inch plastic pipes together. They screw down on the fitting to make a water tight couple. Where can I get these?
    Thanks

    Yep, couplers. If you don't have a good marine supply outfit in your area an RV supply outfit will likely have what you need.
    I purchased most of my potable water fittings from Evergreen RV supply.

      My 4700 is a 2001 model. All of potable water plumbing is 20MM whale brand pipe and fittings

        Thanks for the replies but they are not whale. I should mention my boat was built in Maryland, not Washington, so maybe the fittings are different.

          When I needed fitting for my 1996 4087, I purchased them from a Bayliner dealer, and the cost was not out of line.

            Not 100% sure but they might be Sea Tech https://tinyurl.com/yctwj6y4

              The fittings on my Bellingham-built 1983 3270 are shown below. The gray tubing is one-half inch OD. I bought replacements from a local plumbing shop for a while but was told about 10 years ago that they were no longer available.

                The grey fittings are Qest, here's an example of one supplier.

                  Try a RV supply, many motor homes and RV'S have them.

                    I keep a supply of Tee and 90 degree fitting as well as couplers on my boat. I use either Shark Bite or the Store brand PVC type self locking fitting. I get these from the nearest Home Depot or Lowes in the plumbing section. I also carry a few sections of the 1/2 inch PEX tubing to make repairs. These fitting are reusable but do require a square cut end to seal properly. You Tube using PEX tubing. It also comes in colors for the hot and cold water systems. I don't leave the dock without it for the Potable water system.

                      I found the white couplings/valves at an RV parts store. I think they are called Flair-it. I can't find the link for the specific one I bought, but I did find this: https://www.rvupgradestore.com/Three...5896C014A9FECB

                        Plus one on the Sharkbite fittings. Be sure to get the little release tool for those, you'll probably need it...
